Abstract

A three-dimensional synthesis technique is applied to the design a quasi-optical antenna system which transforms the output of a gyrotron operating in a whispering-gallery mode (WGM) into a Gaussian free-space beam. The two shaped reflector surfaces of the antenna system are synthesized numerically using a procedure based upon geometrical optics principles. An outline of the synthesis technique together with numerical results for a focused Gaussian output are presented.
